# Three.js Post-Processing

## Detailed Guide

Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

## When to Use
- You need screen-space visual effects in a Three.js render pipeline.
- The task involves `EffectComposer`, bloom, depth of field, color grading, blur, or custom passes.
- You are enhancing the final rendered image rather than base scene setup alone.

## Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
